Technical characteristics

The chemical composition of steel 40Х9С2 as defined by GOST 5632-72, The alloy refers to the martensitic class. Its composition includes chromium, nickel, molybdenum, titanium, manganese, copper, as well as carbon 0,4%, phosphorus, sulfur in hundredths percent. Alloying has a multidimensional effect on the quality of steel. Chromium increases hardness and corrosion resistance. Nickel gives the alloy ductility and resistance to impact loading. Manganese content above 1% increases hardness, impact strength, and wear resistance. Titanium increases stability, corrosion resistance; Copper increases ductility, prevents rusting.

C Cu Mn Cr Si Ni S P Ti Fe Impurities
0.35 - 0.45 ≤0.3 ≤0.8 8 - 10 2 - 3 ≤0.6 ≤0.025 ≤0.03 ≤0.2 Basis ≤0.3

This steel grade is used to produce both bar and sheet products. The main advantages of this steel:

  • heat resistance;
  • Resistance to sulfur-containing media;
  • Resistance to the action of wet corrosion.

Application

Engine inlet and outlet valves, recuperator tubes, grates, fasteners. This steel is not used in welded structures. The rolled section, according to GOST 5949-75, has the short-term strength over 740 MPa.
